We're dividing 55267304 by 660 
Let's see how many times 660 fits into 55267304.

On to step 1:
660 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 660

Moving on to step 2:
The number 660 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 660

Let's proceed to step 3:
When dividing 552 by 660, we get 0 with a remainder of 552.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 552 leaves us with 552.
Grab the next digit (6) from the dividend, add it to 552, then carry on: 5526 / 660

On to step 4:
5526 divided by 660 is 8 with a remainder of 246.
The next digit of our result is 8. 
Result so far: 8.0
If we take 5280 away from 5526, we end up with 246.
Bring next digit (7) of the dividend behind the 246 and repeat the process: 2467 / 660

Step 5:
660 goes into 2467 3 times with a remainder of 487.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 1980 from 2467 and we're left with 487.
Take the next digit (3) from the dividend and append it to 487, then repeat: 4873 / 660

Advancing to step 6:
The number 660 fits into 4873 7 times, leaving a remainder of 253.
Write down 7 as next digit of the result. 
Result so far: 837.0
Deduct 4620 from 4873 and we're left with 253.
Append the next digit (0) from the dividend to 253 and continue with: 2530 / 660

Advancing to step 7:
660 can be fit into 2530 3 times, resulting in a remainder of 550.
The next digit of our result is 3. 
Result so far: 8373.0
Subtracting 1980 from 2530 leaves us with 550.
Grab the next digit (4) from the dividend, add it to 550, then carry on: 5504 / 660

Step 8:
660 goes into 5504 8 times with a remainder of 224.
The number 8 becomes the next digit in our result. 
Result so far: 83738.0
Subtract 5280 from 5504 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 9:
2240 divided by 660 is 3 with a remainder of 260.
Record the quotient 3 as the next digit in the result. 
Result so far: 83738.3
If we subtract 1980 from 2240, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
The number 660 fits into 2600 3 times, leaving a remainder of 620.
The next digit of our result is 3. 
Result so far: 83738.33
If we subtract 1980 from 2600, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

The final result is 83738.33 with a remainder of 0.62.
